A VPN is a network technology used for creating a safe and encrypted connection on private networks (owned by service providers) or public links (such as the internet). It creates a secure pathway for users to access websites and applications online while encrypting all sent and received data.

Educational institutions, governmental agencies, and large enterprises use VPN technologies to grant remote users safe access to enterprise applications and other corporate resources. To secure the internet connection, VPN users have to use authentication methods, which include tokens, passwords, and PINs.

Since you establish a "private" connection, the information transmitted from one location to another cannot be read/tracked by anyone else. This ensures all internet activity from users is safe from prying eyes (governmental agencies and third-party service providers). 

In simple words, VPNs are not very different from firewalls that protect your data on laptops/computers. The only difference is; these private networks offer security for information shared “online” via a combination of encryption protocols and dedicated connections.

How Do VPNs Function?

Upon connecting your computer (or any other device like a tablet, smartphone, or laptop) to a VPN, you appear to be on the same local network as the VPN. This allows all your information to pass through a secure connection, even if you are accessing the internet from the other side of the world.

You typically begin using the internet, as if you were present at the VPN’s location, regardless if it is from another country. For instance, if you are using a UK server to access Netflix and unblock your favorite movies/TV shows, your connection will appear to be coming from within the UK.

This offers superb benefits, especially if you are using an unsecured, public Wi-Fi connection, or need to access geo-blocked websites in countries with tough internet laws, like China. Individuals gain the ability to mask their physical location (actual IP address), bypassing all kinds of content filters.

Why Do You Need a VPN?

As a favorite tool for both corporate and home users, VPNs offer a list of unmatched benefits. However, it is imperative that you opt for “Premium” services and avoid those that market themselves as “Free”. A better option would be to sign up with a Cheap VPN service. They charge less and deliver great value to privacy-conscious users, while being of great assistance for:

Improving Digital Security

Nowadays by connecting to the internet, you can make yourself vulnerable to an unlimited number of hackers, malicious programs, viruses, and other unknown threats appearing on a daily basis. This risks interception of the information you send and receive. Using a VPN secures your connection through encryption and masks your IP address, eliminating all instances of data security issues.

Indulging in P2P/Torrenting

In many countries, downloading files via torrents could get you into legal troubles. Connecting to a secure VPN and then using torrent sites rids you of any legal hassles and compliance issues. In fact, if your ISP is throttling torrent software to reduce speeds, using the Best VPN for Torrenting can even get you faster speeds. The same goes true for other types of traffic your ISP might be interfering with.

Leveraging Anonymity Online

By using a VPN, you can browse the web with the utmost level of privacy and anonymity. This ensures you are not easily identifiable by curious individuals, governmental agencies, cybercriminals and aggressive marketing firms who can find your location, address, and name without any effort or hassle.

Improving Connectivity/Speeds

In certain circumstances, your internet routes may not offer optimal bandwidth towards international resources. This results in slow browsing and a poor web experience overall. By connecting to a local server through a service, like the one in this PureVPN Review, you can boost speeds to distant destinations. This is because you gain the ability to access network portals in other countries.

Easing Accessibility to Local Networks

VPNs can be set up to access your local network even while traveling. This enables you to play games with people on your local connection, access a Windows Remote Desktop over the internet, or use local file shares, as if you were on the same LAN network of your home/business.

Wrapping Things Up

With governments, digital products/services, cybercriminals, social media platforms, and even small to mediocre websites, all trying to gain user information – using a VPN has never been more crucial. If you value your anonymity online, these privacy tools are the first step to keeping your identity hidden.
